By the Numbers
Cause → Event → Consequence
Francis I of France sought allies in Central Europe to counterbalance the growing power of Habsburg Emperor Charles V. Sigismund I of Poland was motivated by the threat of Charles V drawing closer to Russia, which endangered Poland on two fronts. Queen Bona Sforza, Sigismund's Italian wife, additionally promoted the alliance in hopes of recovering sovereignty over Milan.
France and Poland concluded an alliance in 1524, negotiated by Antonio Rincon and Jerome Laski. The agreement included a proposed double dynastic marriage linking the royal families and committed Sigismund to support Francis I's efforts to reconquer Milan, to which Sigismund held a claim through his marriage to Bona Sforza.
The alliance collapsed when Francis I was defeated by Charles V at the Battle of Pavia in 1525, rendering the agreement void. Francis subsequently sought new Central European partners after 1526, turning to Hungary rather than Poland and concluding a Franco-Hungarian alliance with King Zapolya in 1528.
Political Outcome
The alliance was signed in 1524 but failed to take effect after France's defeat at the Battle of Pavia in 1525.
Habsburg Emperor Charles V held dominant power in Central Europe with limited French counterbalance.
Alliance collapsed; Habsburg dominance persisted, and France redirected its alliance strategy toward Hungary.
